4 Claims.

This invention relates to a loose leaf binder and particularly to means for facilitating the binding of the back member of the binder.

It is an object of this invention to provide 5 means for securing a pintle sheath to the back member after the back member has been bound. Other objects of this invention will become apparent upon reading the following description taken in conjunction with the accompanying drawings, in which Figure l is a fragmentary perspective view of a loose leaf binder embodying the invention;

Figure 2 is a fragmentary plan view of the binder parts in disassembled position;

Figures 3, 3A, 3B, 3C and 3D are end views of the parts shown in Figure 2;

Figure 4 is a cross sectional view showing the binder in closed position; and

Figure 5 is a cross sectional View taken along the line V--V of Figure 2.

In the drawings the reference numeral 2 indicates a back member along opposite longitudinal edges of which hinge lugs 3 and 4 are suitably secured as by welding or riveting. The inner edges of the hinge lugs 4 are bent, as indicated at 5, to form short channels. The back member is bound with a strip 6 of canvas, leather or other suitable material. The binding material is cut out, as indicated at l and 8, to fit over the hinge lugs 3 and 4. The inner surface of the back member is then covered with a lining 9, which also covers the inner edges of the binding material.

A pintle sheath I is provided with a flange l l which fits into the channels 5. The other edge a of the sheath is curled to form an enclosure l2 for a pintle [3. The sheath I0 is provided with a plurality of notches extending through the enclosure [2, as indicated at l2. An angular strip is welded to the sheath Ill and has projections extending from its free edge curled to form hinge lugs IS. A cover member [6 has secured thereto a hinge plate I! provided with hinge lugs 18 which cooperate with the hinge lugs 4 and It to receive a pair of oppositely directed hinge pins H3. The other cover member 20 is secured to the opposite edge of the back member by means of the hinge 2 l.

A strip 22 is pivotally secured to the back member 2 by means of the hinge 2|. A plurality of sheet retaining posts 23 is rigidly secured to the strip 22. The rigid securement of the posts is of considerable advantage in inserting sheets in the binder. When the empty binder is open the strip 22 may be turned on the hinge to make the posts 23 stand vertically. A plurality of sheets 24, apertured as indicated at 24, may then be impaled upon the posts without difficulty.

The free ends of the sheet retaining posts are apertured, as indicated at 25, and these apertures register with the enclosure 12 when the strip 22 is turned on the hinge 2| so as to position the free end of each post in one of the notches l2. The pintle I3 may then be threaded through the enclosure l2 and the apertures 25 to retain the posts securely.

From the foregoing it will be seen that I have devised simple and inexpensive means for securing a pintle sheath to a binder back after the back has been bound. Heretofore in binders of this type the pintle sheath has been welded or riveted to the back member and the subsequent binding operation has been intricate and costly.

Although I have described one embodiment of my invention in detail, it will be understood that the description thereof is illustrative, rather than restrictive, as many details may be modified or changed without departing from the spirit or scope of the invention. Accordingly, I do not desire to be restricted to the exact details of construction described, except as limited by the appended claims.

I claim:

1. In a loose leaf binder, a back member, a channel member secured to said back member,

a hinge spaced from said channel member, and a pintle sheath having one part engaged with said channel member and another part engaged with said hinge to secure said pintle sheath to said back member.

, 2. In a loose leaf binder, a back member, a plurality of hinge lugs secured along one edge of said back member, said hinge lugs each having one edge shaped to form a channel, a pintle sheath, and means on said pintle sheath cooperating with said hinge lugs and said channels whereby said pintle sheath is secured to said back member.

3. In a loose leaf binder, a back member, a plurality of hinge lugs extending along opposite edges of said back member, a plurality of channels formed on the inner edges of some of said hinge lugs, and a pintle sheath having one edge extended to engage said channels to facilitate securement of said pintle sheath to said back member.

4. In a loose leaf binder, a back member, a plurality of channel members secured to said back member adjacent one edge thereof, one edge of each of said channel members being curled to form a hinge sleeve, and a pintle sheath secured to said back member by means of said channel members and said hinge sleeves.
